Tools, Techniques, and Zero Visibility Archaeology.

Abstract

Growing specialization in the field of nautical archaeology is expanding the boundaries of underwater research. Remote sensing and deep water capability make more wrecks accessible to archaeologists each year. But there is one basic obstacle facing the underwater researcher that "high tech" tools have not completely solved. Individuals who work underwater eventually encounter low or zero visibility conditions where they must not only function but be productive. To work in low visibility proper training, technique, experience, and equipment are essential. The scientific dive training program at East Carolina University tailors its training to research scientists who work in the dark, muddy sounds and rivers of the Southeast. As a result, the University's Program in Maritime History and Nautical Archaeology has successfully excavated and documented a number of historically significant shipwreck sites in difficult diving conditions. This paper will discuss zero visibility training,tools and equipment used to investigate the side wheel paddle steamer Maple Leaf.
